Give the following data for each type of outlet:
Reservoir regulated by spillway gates (items
22, 23, and 24).
a.
Number and type. (Indicate whether tunnel, con-
duit, or weir and whether lined or unlined.)
b. Location. (Indicate whether outlets are through
the mair dam, through an abutment, tunnel
around end, and so on.)
c. Size and shape. (Indicate whether circular, rec-
tangular, or nonsymmetrical and give width and

radial, caterpillar, needle valve, and so on.)
b. Location. (Indicate whether gates are at outlet
entrance, at outlet portal, inside the conduits,
and so on.)
c. Means used to operate gates (gantry crane,
chain lift, screw stem, hydraulic pump, and
so on).
d. Time required to open one outlet gate or valve.
e. Time required to open all outlet gates.
f. Size and shape of gates or valves.
